IPC: G11B7/09
Filed: 1986-07-11
Abstract: PURPOSE:To suppress the movement of an objective and to prevent jitters from being generated, and to improve the SN ratio by providing a projection member to a movable body where the objective is mounted and bringing them into point contact with the opposite surface of a magnetic yoke. CONSTITUTION:This actuator is equipped with the movable body 28 which holds the objective 34, a focusing coil 34 provided on the flank of the movable body 28, a tracking coil 32 fitted overlapping with it, and a magnetic circuit which applies a common magnetic field to both coils 30 and 32.

Title: Radio communication equipment
Inventor: YAMADA MITSUTOSHI
IPC: H04B1/40
Filed: 1984-08-02
Abstract: PURPOSE:To know the state of the station of the remote side when the speech communication is carried out among plural radio stations by means of radio waves, by securing such a constitution where both an own station code and a state code are transmitted automatically prior to the voice call and the radio equipment receives, decodes and displays those two codes. CONSTITUTION:When a certain radio station performs the speech communication with other three radio stations, the relevant radio station transmits the radio wave of a format shown in a figure (a). Then a voice message is transmitted. The received transmission data is demodulated by an FM demodulator 30 and then demodulated by an MODEM24 and then decoded by a decoder 44 to be supplied to a CPU35 through an input port 38. The station code of the transmission side contained in the transmission data supplied to the CPU35 is stored to a reception code memory RAM37 together with a control code CC. The CPU35 decides that the code CC is equal to 1. Then the state of the station of the remote side is displayed as long as the state and the code of the remote side station are displayed at a display device 48 through an output port 39.

Filed: 1987-06-30
Abstract: PURPOSE:To miniaturize a keyboard and to reduce a provided space by displaying on a screen the image of a virtual key having the same arrangement as the key on an input device and judging a data identifier to key input information based on data identifier discriminating information in frame information. CONSTITUTION:On the screen of a display device 2, the virtual key having the same arrangement as the arrangement of the key on a input device 1 is displayed and the virtual names of respective keys in the frame information selected by a frame information selecting means 4 are also displayed on the key by a virtual key display control means 5. When an operator sees the screen of the display device 2 and depresses the key on the input device 1 as the same position as the virtual key during displaying, a data identifying means 6 discriminates the presently inputted data identifier from the information of the depressed key and data identifier discriminating information corresponding to the virtual key during presently displaying added from the frame information selecting means 4. Since plural keys can be used for plural purposes, the input device can be miniaturized.

Title: High resolution visual system
Inventor: BUISHIYUFUJITSUTO SHIN NARUWA
IPC: H04N5/225
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To use a sensor array having a low resolution and a display device having a low resolution (for example, aliquid crystal display device) to project an image having a high resolution. SOLUTION: A visual system has a group of reflection surfaces 42 formed to a pyramid shape 40 which segments the visual field. Each of reflection surfaces 42 formed to the pyramid shape 40 presents a segment of a visual field 82 to a lens 62, and this lens condenses an image segment on a sensor, and this sensor stored data or present the electronic display of the image. The assembly of reflection surfaces 42 formed to the pyramid shape 40 gives a common projection center to individual sensors. Thus, the distortion generated by using plural sensors having different projection centers is avoided. The sensor used for light reception of each segment has a low resolution, but this sensor acquires only a segment (a part) of the image; and therefore, the entire image can be acquired with a high resolution as the whole.

Title: Optical deflector
Inventor: IKUMI TOMONORI
IPC: B41J2/44
Filed: 1989-06-26
Abstract: PURPOSE:To eliminate the need for previously shaping the incident light to the optical deflector to the beam light which is long in a main scanning direction and to reduce the size and weight of various devices for optical scanning by providing a polygon mirror which is narrower in the width of the rotating axis direction of the reflecting surface than the beam diameter of incident light. CONSTITUTION:The optical deflector 21 is provided with the polygon mirror 23 which is narrower in the width of the reflecting surface 22 than the diameter of the exit light of a light emitting device and is formed of, for example, an extremely thin metallic sheet of a polygonal shape. A correcting lens 25 for a face inclination error is disposed between the optical deflector 21 and the surface 24 to be scanned. The width of the reflecting surface 22 of the optical deflector 21 is narrow and, therefore, even if the light of a large diameter is made incident to the polygon mirror 23, the deflected scanning light is small in the beam diameter in a vertical direction. The need for previously shaping the incident light to the polygon mirror 23 to the beam light long in the main scanning direction is, therefore, eliminated for the optical deflector 21. The need for an aperture and cylindrical lens for shaping the beam light is eliminated in this way and the size and weight of the device are reduced.

Title: Hot water feeder

IPC: F24H1/10
Filed: 1993-06-08
Abstract: PURPOSE:To prevent transient temperature variations in a temperature of hot water to be supplied at the time of the time of resuming the supply of hot water by comparing a deviation of a counted value of a temperature of hot water to be supplied from a set temperature in a state that a bypass on-off valve is closed or opened, and controlling the bypass on-off valve so that the deviation becomes smaller. CONSTITUTION:In a hot water feeder A, a bypass on-off valve 5 is controlled to be opened or closed so that a deviation of a counted value of a temperature Tm of hot water to be supplied from a set temperature Ts becomes smaller. That is, a control unit 16 finds the deviation of the counted value of the temperature of hot water to be supplied from the set temperature Ts in the case where the bypass on-off valve 5 is opened or closed, respectively, on the basis of a value Th detected by a thermistor 9 for a temperature of hot water to be supplied and a value Tc detected by a thermistor 7 for a temperature of water to be fed. Then, the control unit 16 compares these deviations E and F with each other and controls the bypass on-off valve 5 to be opened in the case of E<=F or to be closed in the case of E>F. By this method, hot water at a suitable temperature close to the set temperature can be supplied.
